Who said they do? I don't like him. He's the most overrated derp in the world.
I think people who hate MJ because "lawl he's a pedophile" are morons. I couldn't care less about HIM. It's about his music/singing/performance/whatever. It's about him as an artist, not about his personal life and shit. And personally, I disliked all his shit. It's not that I don't accept that taste is subjective; I do, and I respect that you can like him, but I hardly see why he's perceived to be a god or something. He's just another performer.
TL;DR All the "controversies" and shit about him are useless derp. Seriously, people. Grow up. Be you fans or haters, just grow the fuck up and forget about it.
